The usage of birdnest increased dramastically since the beginning of June. Now we get more than 100,000 hits daily, mostly from China, and takes more than 10GB/month. So impressive this little service can be useful for many people over the world.

Anyway, I have to redeploy birdnest in wsgi mode to lighten the server load because the increasing of #birdnest usage. After some test drive, I migrate nest.onedd.net to wsgi over Phusion Passenger. Even though its wsgi support is just proof-on-concept, the performance is quite impressive. Kudos to Passenger team.
Thanks to @sugree, @iake, @tewson, @jittat and everyone for testing and give me bug report and other feedback. Feedback and suggestion are welcome at Project homepage.
